Patented May 27, 193() REBECCA E. HoorER, or HALE Moon BAY, cALIEoENm iMEMORY Y rAn Application filed November 14, 1927.` Serial No. 233,230.

My invention relates to improvements in memory` pads, and it consists inthe combinations, constructions and arrangements hereinafter describedand claimed.

An object of my invention is to provide a memory pad that has means forcovering a portion of the work, causing the student tot recall frommemory the portions of the work thus covered and which has means foradvancing the work covering shield sothat an entire sheet of paper maybe systematically gone over in order that by constant repetition thenecessary problems will become memorized. The device maybe used for allkinds l "V of problems, the learning of shorthand being one of thespecial uses to which the device may be put.

The invention employs several features which differ from other devicesnowon the market. A guide for a ruler is so mounted that this guide maybe moved vertically with respect to the pad. I term this member aHeating guide. The second feature is the provision of a stop for theruler that-may be 5 swung into inoperative position when it is desiredto remove the ruler from the topmost sheet of the pad in order that thissheet may be torn from the pad. A third feature resides in the postswhich perform a double function. These posts clamp a pad of anythickness within predetermined lines to the suppor, andalso act asuprights for the floating u1 e. h Other objects and advantages willappear in the following specification, and the novel features of myinvention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a partof this ap- 0 plication, in which:

Figure 1 is a top plan view of the device; Figure 2 is a section alongthe line 2-2 of Figure 1; and

Figure 8 is a section along the line 3-3 of Figure 1.

In carrying out my invention I provide a supporting back 1 that can bemade of any desired material that is strongl enough to withstandordinary school use. To this support I secure posts 2, the posts oruprights being disposed at the rightand left hand up* per corners of thesupport. These posts have heads 3, seeFigure 35 that prevent the postsfrom being withdrawn from the support 1.

VThe posts are threaded for receiving knurled Vnuts 4. Sleeves 5 arealso mounted upon the `posts 2 and bear against a strip 6 that clamps apad `7 to the supportl.

Itrwilly also be noted from Figure 8 that the postsV not onlypassthrough slots 8 in the support 1, but pass through openings 9 in a`metal strip 10 that is disposed at the back of the support, as Ashownin Figure 2. A tightening of the nuts 4 will cause the sleeve 5 to clampthe strip 6 down against the pad 7 i i A ruler 11 extendsat right anglesfrom the strip 6 and is mounted upon a carriage 12 that has rollers 13for slidably receiving a floating guide member 14. Theruler hasperforations 15 for receiving the point of a pencil whereby a movementof the ruler will draw a line upon thepad 7. Additional perforations 16may be disposed at spaced intervals, such as, for example: one inch`apart. A scale is also stamped upon the rulerand `is indicated by thereference numeral 17. v

The strip 6 also has a scale' 18 thereon. Figure 3 shows how the member14 mounted upon the collars 5 so as to automatically adjust itselfat thedesired height `above the pad 7. i i

The strip 10` carries a clip 19 for receiving a pencil 20. The bar 14carries a grooved collar 21 that is slidably mountedon the sleeve 5.`This collar rotatably receives a stop 21 that is adapted to enter arecess 22 in the carriage 12 whenthe stop is disposed in the positionshown in Figures 1 and 3. This prevents the ruler from being moved offthe pad. The stop maybe swung about the collar 21. When the stop isswung to the left the carriage 12 may be moved so as to receive the post2 in the slot 22. The carriage will carry the ruler 11 clear ofthe pad7. This permits a sheet to be torn from thepad, if desired. The purposeof the stop is to keep the carriage from `riding `olf from the pad. Thismakes it easy for the studentA to quickly move the ruler over thesurface ofthe paper Without is slidably any chance of the ruler becomingengaged with the edge 24 of the pad.

A shield indicated by the dotted line in Figure 1 is removably securedto the ruler 11 by clips 26.

From the foregoin description of the various parts of the dev1ce,tl1eoperation thereof may be readily understood.

A pad of any desired thickness maybe secured to the support 1 b the stri6 and the posts and nuts 2 and 4s. f desiY the shield 25 ma be dispensedwith and the ruler` 11 used or the drawing of a number of lines upon theuppermost sheet of the pad 7. The scales 17 and 18 permit these lines tobe drawn in a predetermined manner.- If it is desired to draw lines atan angle over the pad 7 the pad may be swung into the desired angle andthen be clamped in place.

gg The device is especially adapted fermemory workand when used in thisconnection the shield 25 is secured to the ruler 11 by the clips 26. At27 I have shown shorthand characters and words representing thesecharacters. The student would Write the words but, can, and it afterglancing at the shorthand characters in the row 28. The row 28 wouldthen be covered by the ruler 11 and thon the shorthand characters wouldbe Written in the row 29.- Any number of rows may be provided in thisWay, and the ruler advaneed to cover each row in order that the studentmay ix firmly in mind the various characters represented by the words.

I have already shown a problem at 30 which shows another use for thepad. The device may be used for purposes other thanthose shown, as forexample: thedevice may be used as an ordinary composition tablet inwhich lines have been previously drawn on the paper b inserting thepoint yof a encil in any one o the desired openings 15 an movt e ruler11 transversely across the pad.

Although I have shown and described one embodiment of my invention, itis understood that the same is susceptible of various changes and Ireserve the right to employ such changes as may come within the scope ofthe app en I claim:

1. A device ofthe type described, comprising a. support, uprightscarriedby said support, means carried by said uprights for clamping apad tosaid support, a floating guide bal* slidably carried by said uprights, astop carried by one of said uprights, a ruler, means fo slidablyconnecting said ruler` to said gide bar, said stop normally preventingthe movement of said ruler o from the pad, said stop being movable intoinoperative po; sitn for' permitting the ruler to move olf from the pad.
